Combined Defence Services Exam is an exam conducted by UPSC twice every year. It is a written exam and candidates who clear this exam are called for a personality test called the Service Selection Board. Given below is the syllabus for this exam. There are three papers in this exam English, General Knowledge and Mathematics.

English:  There is no specific course for English. The paper is intended to check the basic understanding of the candidate of English Language. The paper consists of unseen passages, synonyms, antonyms, sentence corrections, ordering of sentences and catching the grammatical errors.

GK: General Knowledge comprises of the toughest part of CDSE or any UPSC exam for that matter. In GK candidates are asked about the recent happenings (of around a period of one to one and a half year). Questions are asked from Polity, Geography, History, Science, Economy etc. You need to have a good understanding of the basics. You can refer to good books dedicated to CDS exam and to the mock and previous years papers to get a rough idea of GK and types of questions.
